Patent

CA 2328465

The invention relates to cosmetic and pharmaceutical cremes in the form of a water in oil emulsion comprising an oil phase with an interfacial tension in relation to water of less than 30 mN/m at 25 ~C, preferably less than 10 mN/m and lipophilic emulsifiers with an HLB value of less than 6. Said cremes can be stabilized by non-densifying starches or derivatives of modified starches with a 1 wt. % solution or dispersion in water that has a viscosity of less than 10 mPas (whereby D = 10/s and at 25 ~C). As a result, ionic and hydrophilic non-ionic emulsifiers are not required at all.

L'invention concerne des crèmes cosmétiques et pharmaceutiques sous forme d'émulsion eau dans l'huile, comportant une phase huileuse dont la tension interfaciale vis-à-vis de l'eau se situe en dessous de 30 mN/m, de préférence en dessous de 10 mN/m, et des émulsifiants lipophiles à équilibre hydrophile-lipophile inférieur à 6. Ces crèmes peuvent être stabilisées par des amidons ou des dérivés d'amidon modifiés, non épaississants, dont la solution à 1 % en poids ou la dispersion dans l'eau présente une viscosité inférieure à 10 mPas (avec D = 10/s et à 25 ·C), de manière que l'utilisation d'émulsifiants ioniques et non ioniques hydrophiles devienne totalement superflue.
